Is the Model 3 equipped with run-flat tires?

Model 3 does not use run-flat tires but rather noise-reducing tires. The tires used on Model 3 come from various brands, such as Continental, Hankook, and Michelin. The tire specifications are 235/45R18 and 235/40R19, and this vehicle does not come with a spare tire. Tesla Model 3 tire pressure: The official manual recommends 2.9 bar, with a suitable range of 2.9-3 bar. Additional information: The dual-motor version of Model 3, when equipped with the battery, weighs only 1,700 kilograms, resulting in a higher load on the tires. The top speed of the dual-motor version is 155 mph. During acceleration or regenerative braking, it is also necessary to ensure continuous torque output.

The original tires on the Model 3 are not run-flat tires, and I can share this from personal experience. I've been driving the Model 3 for several years and noticed right after purchase that it uses regular low-pressure tires. Once, when I had a flat tire on the road, I had to pull over immediately to change the spare tire, which was a real hassle. Tesla does this mainly to control costs and reduce weight, thereby extending the electric vehicle's range. If you want to switch to run-flat tires, you'll need to pay for the upgrade yourself, costing about 5,000 yuan for a set. Although run-flat tires can keep driving for dozens of kilometers after a puncture, they are heavier and stiffer, affecting comfort and energy consumption. I recommend regularly checking tire pressure and keeping an inflatable tire repair kit in the car—it's much more cost-effective than run-flat tires.

From a technical perspective, the Model 3 comes standard with non-run-flat tires that are optimized for either high performance or energy efficiency. Run-flat tires, known as zero-pressure continuation tires in the industry, feature reinforced sidewalls. Tesla likely avoided them to prevent hindering the electric vehicle's acceleration performance. Many Model 3 owners I've encountered who upgraded to run-flat tires complained of over a 10% reduction in range and increased vibration. Standard tires are simpler and cheaper to repair, usually costing just a few hundred yuan, but require immediate attention when punctured. If you frequently drive on highways, it's advisable to carry a spare tire or an inflator kit as a precaution.

Safety is a core concern: The Model 3 typically does not come with run-flat tires, which means you have to brake immediately in case of a tire blowout. Run-flat tires allow you to continue driving 50-80 kilometers to a service point even when tire pressure is unstable, reducing the risk of accidents. Tesla may not include them as standard to save costs and maintain lightweight design, but remember to check tire conditions to prevent blowouts. When using the Model 3 daily, it's advisable to avoid potholes to minimize emergencies and keep onboard tools ready to ensure driving safety.
